Toggle dowsn't switch (visually) if there is a "SetState()" inside "onToggle"

Describe the bug A clear and concise description of what the bug is. I need to change the value of a variable (to show/hide options) when the user presses the Toggle.

To Reproduce Complete runnable code to reproduce the bug/issue.

           ToggleSwitch(
                  minWidth: 150,
                  initialLabelIndex: 0,
                  totalSwitches: 2,
                  labels: const ['FACE-TO_FACE', 'NON-FACE-TO_FACE'],
                  onToggle: (index) {
                    print('switched to: $index');
                    setState(() {
                      faceToFace= index!;
                    });
                  },
                )

Expected behavior A clear and concise description of what you expected to happen. The visual change is expected to act as normal, the same as when the "SetState" is not included
